Scientific workflow management and the Kepler system
Characteristics of and requirements for scientific workflows as identified in a number of application projects are described, and some key features of Kepler and its underlying Ptolemy II system, planned extensions, and areas of future research are described.

The Kepler scientific workflow system provides domain scientists with an easy-to-use yet powerful system for capturing scientific workflows (SWFs), a formalization of the ad-hoc process that a scientist may go through to get from raw data to publishable results.
XML-based information mediation with MIX
The MIX mediator system, MIX, uses XML as the common model for data exchange and employs XML DTDs as a structural description (in effect, a “schema”) of the exchanged data to facilitate user-friendly query formulation and for optimization purposes.
An Ontology-Driven Framework for Data Transformation in Scientific Workflows
This paper defines a generic framework for transforming heterogeneous data within scientific workflows, which relies on a formalized ontology, which serves as a simple, unstructured global schema.
A Transducer-Based XML Query Processor
Rewriting queries using views with access patterns under integrity constraints
Special Issue: The First Provenance Challenge
A functional magnetic resonance imaging workflow was defined, which participants had to either simulate or run in order to produce some provenance representation, from which a set of identified queries had to be implemented and executed.
Scientific Workflows: Business as Usual?

- 27 August 2009
An introduction and overview of scientific workflows is provided, highlighting features and important concepts commonly found in scientific workflow applications and proposing a number of research opportunities for cross-fertilization between the scientific workflow and business workflow communities.
Actor-Oriented Design of Scientific Workflows
- S. Bowers, Bertram Ludäscher
- Computer ScienceInternational Conference on Conceptual Modeling
- 24 October 2005
This work develops a formal model for scientific workflows based on an actor-oriented modeling and design approach, originally developed for studying models of complex concurrent systems, and extends this framework by introducing a novel hybrid type system.
The Open Provenance Model (v1.01)
The Open Provenance Model is introduced, a model for provenance that is designed to meet the following requirements: to allow provenance information to be exchanged between systems, by means of a compatibility layer based on a shared provenance model.
